"Created as a unique piece, The Billionaire truly epitomises the brand's passion for breaking boundaries," reads the Jacob & Co blurb on its website.

"As the tourbillon calibre brings dynamism to its bejewelled enclosure, or the ballet of light of 260 carats of diamonds illuminates its exquisitely revealed heartbeat."

If that means anything to you, then you're perfectly fluent in the kind of high-end luxury hogwash that only salesman of ridiculously expensive hyper cars can speak.

So what exactly do you get for your money? Reading between the lines on the Jacob & Co spec sheet, it seems like other than the copious amounts of diamonds, nothing more than what you would get in a regular analog watch.

Sure, the movement is handcrafted from tiny gears and jewels, but you only get 72 hours of power before it needs to get re-wound again.

(In fairness, that's almost double the time you'd get out of a corner-store wind-up watch, but still disappointing for something that sets you back $18 million.)

There's only one of these watches in known existence, so you better start saving now if you ever hope to see it on your wrist.
